Cal 2-24 vs Cal 21: the short version
- The Cal 2-24 is the larger boat at 24.0 ft7.32 m LOA versus 20.5 ft6.25 m for the Cal 21.
- The Cal 2-24 is heavier, displacing about 236% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Cal 21 carries the more powerful rig (29.4 vs 18.1), favouring lighter-air performance.
- The Cal 2-24 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Cal 2-24 rates better for offshore work (2.00 vs 2.58).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
